What is a neurodegenerative disease?

A neurodegenerative disease is a medical condition characterized by the progressive degeneration of the structure and function of the nervous system, particularly neurons in the brain and spinal cord. These diseases, such as Alzheimer's, Parkinson's, and Huntington's, often lead to a decline in cognitive, motor, and other neurological functions over time. The exact causes can vary, but they often involve a combination of genetic, environmental, and lifestyle factors. Treatment primarily focuses on managing symptoms, as there is currently no cure for most neurodegenerative diseases.
